System Description:

Each Model 1401 Oxygen Analyzer System consists of a zirconium oxide fuel sensor mounted in a heavy duty probe with lengths from 18" to 12 feet (0.5 to 6 meters), electronics in a NEMA 12 enclosure. The 1401 is designed to provide accurate, continuous oxygen measurements on a long term basis with a minimum of maintenance. In the event of a component failure, the probe can be easily disassembled in the field, and the fuel cell sensor, heater, and temperature sensor assembly can be quickly and easily replaced. Costly downtime awaiting factory repairs can be avoided.

For Hazardous location applications a Class I, Group C&D, Class II, Groups E,F&G enclosure is available.

Features:

Reliable - Measurements are made on "wet, total sample basis" using the well known Nernst equation. Zirconium oxide fuel cell measurement of oxygen is currently used in installations worldwide.

5 Micro Diffusion Element - The reusable diffusion element is easily removed for cleaning.

On-Line Calibration - The oxygen sensor cell can operate for months without calibration, however a inlet port is available to test the system with certified gases.

No Sample Lines- No sample lines to clog, leak, dilute or slow system response time.

Low Maintenance- Long term, continuous operation with a minimum amount of operator intervention. All sensor components are easily assessable and can be field serviced utilizing EMS cell kit assembly.

Each system includes:

• Zirconium Oxide Sensor mounted in a S.S. probe
• Electronics in NEMA 12 Enclosure.
• Installation manual

Options:

• Remote control unit with anolog or digital meter.
